Abstract (en)

An anti-penetrant composition, used as a pre-treatment before dyeing of hair, comprises a polyethylene glycol, a block polymer of ethylene and propylene oxides or a copolymer of polyethylene glycol and dicyclohexylmethane diisocyanate. The composition for capillary pre-treatment, in a suitable physiological medium, comprises a quantity greater than 5% of an oxyethylenated polymer from the group: (a) polyethylene-glycols of general formula H(OCH2CH2)nOH (1); (b) block sequenced polymers of ethylene and propylene oxides of formula HO-(CH2CH2O)x-(CH(CH3)-CH2O)y-(CH2CH2O)z-H (2); (c) a copolymer of polyethylene glycol with 8 successive ethylene oxide groups and dicyclohexylmethane diisocyanate of formula HO((C2H4O)8-(C15H24N2O2)-(C2H4O)8)xH (3) and the mean molecular wt. is 1800 g/mol; (d) and mixtures of two compounds a, b and c. n = greater than 45 and less than 795; x and z = such that at least one is greater than 75; and y = greater than 30; x = 1 - 4. An Independent claim is also included for the process for limitation of dye penetration in the skin.

Abstract (fr)

La présente invention concerne d'une manière générale une composition anti-pénétrante de prétraitement capillaire comprenant une quantité efficace d'au moins un copolymère oxyéthyléné. L'invention concerne également un procédé pour limiter la pénétration dans la peau et/ou les fibres kératiniques d'au moins un colorant contenu dans une composition de coloration capillaire, consistant à appliquer en prétraitement sur les cheveux une telle composition antipénétrante, avant le processus de coloration des cheveux.
